Made available via the Publications (Legal Deposit) Act 2004 (NT).; On 27 October 2015, TNG Limited (TNG) submitted a Notice of Intent to the Northern Territory Environment Protection Authority (NT EPA) outlining a proposal for Darwin Refinery. TNG proposes to construct and operate the Darwin Refinery on Middle Arm, Darwin Harbour, adjacent to the Elizabeth River (within Lot 1817, Hundred of Ayers). The refinery would process magnetite concentrate railed from TNG’s (separately proposed) Mt Peake Project, 1,400 km south of Darwin. Terms of Reference to assist the proponent in preparing the draft EIS for Darwin Refinery were issued on the 20 May 2016.


TNG Limited (TNG) submits this Notice of Intent (NOI) to the Northern Territory Environment Protection Authority (NT EPA) and Department of Lands Planning and Environment (DLPE) as formal notification of its proposal to construct and operate the Darwin Refinery (Refinery).

TNG Limited - Darwin Refinery EIS Terms of Reference NORTHERN TERRITORY ENVIRONMENT PROTECTION AUTHORITY 16 associated with Project activities such as site preparation, component construction, introduction of construction materials to the site, loading / unloading activities, stormwater management of uncontrolled contaminated discharge, including the failure of proposed mitigation measures of alteration of hydrology and rates of erosion / sedimentation of waterways of disturbance of potential acid sulfate soils of any additional impacts to surface water and / or groundwater resulting from the Project o to the Beneficial Uses, Water Quality Objectives and identified environmental values o to the food chain, particularly species that are consumed by people. of unsustainable use, and/or wastage of water resources. A water-balance and water management plan should be provided for the Project. The influence of seasonality and annual variability should be discussed where relevant. The risk assessment should consider short, medium and long term timeframes of the Project. Provide a groundwater and surface water contaminant transfer model for the Project site, to predict potential contaminant transport dynamics over time, and in response to alternative management actions and infrastructure configurations. Provide design specifications of facility components to indicate the magnitude of flood event the components will be designed to withstand. For example, indicate the average recurrence interval (ARI) flood categories for which the water process dam will remain a secure nodischarge facility. Particular details on the location of the process water dam in relation to storm surge should be provided and details on whether water from the dam will meet ANZECC guidelines if there is ever a need to dispose of excess water and, if not, what safe disposal measures are being proposed. Where identified risks to water quality and related sensitive receptors occur for the Project, interactions should be illustrated in a Conceptual Site Model for the Project (Section 5). 4.3.3 Mitigation and monitoring The EIS should provide management measures aimed at ensuring the environmental objectives are achieved and the Beneficial Uses and Darwin Harbour Water Quality Objectives are maintained. The EIS should outline measures proposed for the efficient and appropriate use of water, including for example the use of alternative sources and re-use opportunities. The EIS should outline the design of stormwater management systems relevant to the local meteorology, including capacity and resilience of any existing natural drainage systems that will be implicated in stormwater management. Provide a discussion on the likely effectiveness of safeguards.
